Device for the digital shape control of profiles

摘要

The traditional shape control of ships' frames, deck beams etc. is carried out using templates which are often prepared in accordance with loft lines. The production of control templates is very costly. A further disadvantage is that only the accuracy of the shape can be checked using the control templates. It is further known that profiles are shaped using the method of the inverted line. The disadvantage of this method is that longitudinal and transverse shrinkage influence the dimensional accuracy of the degree of shaping. The invention seeks to provide a remedy. The invention is based on the problem of providing a device for the digital control of shaped profiles, in particular of ships' frames, deck beams, etc. which makes possible the control of their accuracy as regards shape and their dimensional stability by measuring the profile contour at the moulding edge at arbitrarily freely selectable distances. The measurement itself is controlled using a computer (eg. a PC) and is evaluated in a manner suitable for the data by means of specially prepared software. In order to enable mechanised quality control in the production of ship parts, a pick-up table and a measuring table are arranged on the moulding edge of the shaped profile at freely selectable locations, each table having a wind-up device for accommodating a measuring wire and measuring and guide rollers and clamping elements and a traveller having measuring rolls arranged above and lateral sliding and guide rollers is used in such a manner that it ...
